Promise Dot Try for Improved Error Handling

Promise dot try is an upcoming feature that enhances JavaScript's promise handling capabilities. It allows developers to run functions that may or may not return a promise while still being able to catch any errors thrown. This is particularly useful as it simplifies error management without the need for additional boilerplate code, making it easier to handle mixed promise states. Currently in stage three, promise dot try is seen as a low-risk addition that can streamline error handling in asynchronous code.
